Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. A distributed antenna system, comprising: a first set of remote units configured for transmitting wireless signals in a coverage area; a second set of remote units configured for receiving wireless signals from the coverage area, the first set of remote units being different in number than the second set of remote units; and a central unit configured for communicatively coupling to the first set of remote units and the second set of remote units, and for communicatively coupling to a base station; wherein at least one of: a remote unit of the first set of remote units is configured for only transmitting wireless signals in the coverage area; or a remote unit of the second set of remote units is configured for only receiving wireless signals from the coverage area.
A distributed antenna system has a central unit connected to a base station and two sets of remote units covering an area. The first set transmits wireless signals, and the second set receives them. Critically, the number of transmitting remote units is different than the number of receiving remote units. At least some remote units are transmit-only or receive-only.
2. The distributed antenna system of claim 1 , wherein the first set of remote units and the second set of remote units are configured for independently and directly communicatively coupling to the central unit.
The distributed antenna system described where there is a central unit connected to a base station and two sets of remote units covering an area (one set transmits, one set receives, and the numbers are different), ensures the transmitting and receiving remote units communicate independently and directly with the central unit. There are no intermediate hops between a remote unit and the central unit.
3. The distributed antenna system of claim 1 , wherein the first set of remote units and the second set of remote units are configured for communicatively coupling to the central unit in one or more clusters, wherein a cluster includes a node remote unit configured as a receiver or a transmitter that is communicatively coupled to the central unit and to one or more member remote units, each member remote unit being one of the first set of remote units or one of the second set of remote units.
The distributed antenna system described where there is a central unit connected to a base station and two sets of remote units covering an area (one set transmits, one set receives, and the numbers are different), groups the transmitting and receiving remote units into clusters. Each cluster has a "node" remote unit (either a transmitter or receiver) directly connected to the central unit. One or more "member" remote units (either transmitters or receivers) connect to the central unit *through* that node.
4. The distributed antenna system of claim 1 , wherein the central unit is configured to transmit wireless signals received from the base station to the first set of remote units, and wherein the central unit is configured to transmit the receive wireless signals received from the second set of remote units to the base station.
The distributed antenna system described where there is a central unit connected to a base station and two sets of remote units covering an area (one set transmits, one set receives, and the numbers are different), defines how the central unit handles signals. It receives signals from the base station and forwards them to the transmitting remote units. It also receives signals from the receiving remote units and forwards them back to the base station.
5. The distributed antenna system of claim 1 , wherein a remote unit of the first set of remote units or the second set of remote units is integrated with the central unit.
The distributed antenna system described where there is a central unit connected to a base station and two sets of remote units covering an area (one set transmits, one set receives, and the numbers are different), can integrate one or more of the remote transmitting or receiving units directly *into* the central unit hardware. This reduces the number of physically separate remote units.
6. The distributed antenna system of claim 1 , wherein the first set of remote units is configured to utilize a first subset of supported frequency bands, wherein the second set of remote units is configured to utilize a second subset of the supported frequency bands, the first subset of supported frequency bands being different from the second subset of supported frequency bands.
The distributed antenna system described where there is a central unit connected to a base station and two sets of remote units covering an area (one set transmits, one set receives, and the numbers are different), assigns different frequency bands to the transmitting and receiving remote units. The transmitting units use a first set of frequencies, while the receiving units use a different, non-overlapping set.
7. The distributed antenna system of claim 6 , wherein a first remote unit of the first set of remote units is configured to utilize a first transmission band of the first subset of supported frequency bands and a second remote unit of the first set of remote units is configured to utilize a second transmission band of the first subset of supported frequency bands, the first transmission band being different from the second transmission band.
The distributed antenna system that assigns different frequency bands to the transmitting and receiving remote units ensures that different transmitting remote units use different frequencies *within* the assigned band. One transmitter uses frequency A, and another transmitter uses frequency B, both from the overall frequency band assigned to transmitters. This allows for greater capacity or reduced interference.
8. A distributed antenna system, comprising: a central unit configured for communicatively coupling to a first set of remote units and a second set of remote units and for supporting one or more transmission bands and one or more receiving bands; the first set of remote units configured to utilize a first subset of the one or more transmission bands; and the second set of remote units configured to utilize a second subset of the one or more receiving bands, the first subset of the one or more transmission bands being different in number than the second subset of the one or more receiving bands.
A distributed antenna system uses a central unit connected to a set of transmitting and receiving remote units. The central unit supports specific transmission and receiving frequency bands.

One or more "member" remote units (either transmitters or receivers) connect to the central unit *through* that node.
11. The distributed antenna system of claim 8 , wherein the first set of remote units are different in number than the second set of remote units.
The distributed antenna system that uses different subsets of transmission and receiving bands, uses a different number of transmitting remote units compared to receiving remote units. There are more transmitters than receivers, or vice-versa.

The distributed antenna system that uses different subsets of transmission and receiving bands, specifies signal flow. The central unit sends cellular data from a base station to the transmitting remote units, which then broadcast the data. The receiving remote units listen for signals and forward them back to the central unit.
13. The distributed antenna system of claim 8 , wherein one of the first set of remote units or one of the second set of remote units are configured to be integrated with the central unit.
The distributed antenna system that uses different subsets of transmission and receiving bands, integrates one or more of the remote transmitting or receiving units directly *into* the central unit hardware. This reduces the number of physically separate remote units.
